Tshooj 2 ntawm cov hlwb hnub ci

Gallium arsenide (GaAs) Ⅲ ~ V roj teeb sib xyaw ua ke hloov pauv efficiency txog li 28%, GaAs cov khoom sib xyaw muaj qhov sib txawv zoo heev ntawm cov kab sib txawv, nrog rau kev nqus tau zoo, muaj zog tiv taus kev cuam tshuam, tsis hnov ​​​​​​mob kub, tsim nyog rau kev tsim cov roj teeb ib leeg ua haujlwm siab. Txawm li cas los xij, tus nqi ntawm GaAs cov ntaub ntawv tsis kim, yog li txwv tsis pub GaAs roj teeb nrov rau ntau qhov.

Lub roj teeb tooj liab indium selenide nyias zaj duab xis (CIS luv luv) yog tsim rau kev hloov pauv photoelectric, tsis muaj kev lag luam photoelectric, kev hloov pauv zoo thiab polysilicon, nrog rau tus nqi qis, kev ua tau zoo thiab kev yooj yim ntawm cov txheej txheem thiab lwm yam zoo, yuav dhau los ua qhov kev taw qhia tseem ceeb rau kev txhim kho yav tom ntej ntawm lub hnub ci hlwb. Qhov teeb meem tsuas yog qhov chaw ntawm cov ntaub ntawv, vim indium thiab selenium yog cov ntsiab lus tsis tshua muaj, yog li ntawd, kev txhim kho ntawm cov roj teeb zoo li no yuav raug txwv.
(3) cov roj teeb hnub ci polymer organic
Cov organic polymers hloov cov khoom siv inorganic yog ib qho kev tshawb fawb ntawm kev tsim cov roj teeb hnub ci. Vim tias cov khoom siv organic muaj kev ywj pheej zoo, yooj yim ua, ntau yam khoom siv, pheej yig thiab lwm yam zoo, yog li kev siv lub zog hnub ci ntau, muab hluav taws xob pheej yig yog qhov tseem ceeb heev. Txawm li cas los xij, kev tshawb fawb txog cov khoom siv organic los npaj cov roj teeb hnub ci nyuam qhuav pib, txawm tias nws yog lub neej ua haujlwm, lossis kev ua haujlwm ntawm lub roj teeb tsis tuaj yeem piv rau cov khoom siv inorganic, tshwj xeeb tshaj yog cov roj teeb silicon, seb nws puas tuaj yeem tsim kom muaj txiaj ntsig zoo ntawm cov khoom, tab sis kuj yuav tsum tshawb nrhiav ntxiv.
(4) cov hlwb hnub ci nanocrystalline (cov hlwb hnub ci uas muaj xim zas)
Nano Ti02, cov roj teeb hnub ci siv hluav taws xob crystalline tshiab tsim, nrog tus nqi pheej yig thiab cov txheej txheem yooj yim thiab kev ua haujlwm ruaj khov. Nws cov photovoltaic efficiency ruaj khov ntawm ntau dua 10%, tus nqi tsim khoom tsuas yog 1/5 ~ 1/10 ntawm cov roj teeb hnub ci silicon, lub neej ntev tuaj yeem ncav cuag ntau dua 20 xyoo. Txawm li cas los xij, txij li thaum kev tshawb fawb thiab kev txhim kho ntawm cov roj teeb zoo li no nyuam qhuav pib, nws tau kwv yees tias lawv yuav maj mam tuaj rau hauv kev ua lag luam yav tom ntej.
